LAY OF LOOIV'IS.

SPECIFICATION forming part of Letters Patent No. 789,343, dated May 9, 1905.

Application filed Novmlwl l2, 1904- Selial No. 232,410.

T0 1J/Z whom it vim/y concern:

Be it known that I, WILLIAM VATTIE, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in. Lays of Looms, of which the following is a specication.

My invention relates to the lay of a loom, and more particularly to an improved construction of the layebeam in a heavy loom.

In the ordinary construction oi' a lay the lay-beam consists of a wooden beam. In order to ob tain suiiicient rigidity and strength, it is necessary to use a beam of large dialneter in cross-section, and even in the case of heavy beams the same are liable to warp and get out of shape, and thus interfere with the proper throw ofthe shuttle through the shed.

The obj ect of my invention is to improve upon the construction of a lay-beam, particularly in a heavy loom oi the cottonduck or woolen type, and to provide a lay-beam made of metal, preferably steel or iron, and preferably comprising two independent metal bars of angle shape in cross-section, secured together or secured to intermediate blocks in such amanner tl iat one of the angle metal bars will form the raceway and the front of the lay-beam and the other will form the bottom and the rear oi the lay-beam. The bottom reed-supporting bar will extend below and at the rear of the upper side of one metal anglebar.

My invention consists in certain novel ifeatures oi" construction oit my improvements, as will be hereinafter fully described.

I have only shown in the drawings a detached portion of one end ol' a lay embodying my improvements, sul'iicient to enable those skilled in the art to "understand the construction and operation of the saine.

Referring to the drawings, Figure 1 is a :front view oi the right-hand end of a lay detached lembodying my improvements and showing a portion of the shuttle-box stand and guide. Fig. 2 is a section on line 2 2, Fig. 1, looking in the direction of arrow e, same iigurc. Fig. 3 is a horizontal section taken at a point indicated by line 3 3, Fig. l, looking in the direction of arrow l), same figure. Fig. 41 is a rear view of the central portion of a lay broken away and showing the recess for the filling feeler-iiork looking in the direction oi arrow c, Fig. 5. Fig. 5 is a section on line 5 5, Fig. 4, looking in the direction of' arrow d, same ligure. Fig. 6 is a plan view of the end oi' the handerail shown in Fig. 1 looking in the direction oi arrow b, same figure. Fig. 7 is an end view oil one of the blocks or braces detached looking in the direction of arrow e, Fig. 8, which Yform a part of the lay. Fig. S is a side view of the brace shown in Fig. 7 looking in the direction of arrow j', saine iigure. Fig. 9 corresponds to Fig. 1, but shows a modiiicd construction of the lay-bea1n; and Fig. 1() is a section on line 10 10, Fig. 9, looking in the direction of arrow g, same iigure.

In the accompanying drawings, 1 is the upper end of the lay-sword, which in this instance has connected with it a shuttle-box stand and guide-plate 1 and the lay-horn 1 and the rearwardly-extending ears 1 for the connector to the crank-shaft and the forwardly-extending projection 1, inwardly curved at its liront end to forni the end of the lay-beam, and also the support l, extending inwardly. i A

The support 1L is preferably made as shown, having at each end the horizontal tubular parts 1i, connected by a web 1u, and also at each end a vertically-extending tubular part 1, connected by a vertical web 1. Extending out -from the iront ol the vertical tubular parts 1 are the web portions 1. Extending -from the horizontal tubular parts 1 are the vertical web portions l, the height of which are about onehalf the height ot' the front web portions 11". (See Fig. 2.)

Extending upon the top and 'front side of the support 1L is a metal bar 2, made oi? iron or steel and oi angle shape in cross-section, which forms the top or race elt the lay and also the 'front side oi' the lay. The end ol' the 'iront side of the angle-bar 2 meets and butts against the iront edge of the projection 1,

and the top of said bar 2 extends over said projection, as shown in Fig. 1.

Upon the under side and rear part of the support 1EL extends a second metal angle-bar 3, corresponding to the metal angle-bar 2 and forming the under side and rearside of the lay-beam. The angle metal bar 2 and the angle metal bar 3 extend the full length of the lay, and the opposite ends thereof (not shown) are attached to a support corresponding to 1 on the lay-sword on the other end of the lay.

The angle metal bar 2 is attached at its upper side to the support 1LL and also to the angle metal bar 3 and held in position thereon in this instance by a bolt 4 extending through each of the vertical tubular parts 16 and secured therein by a nut 4 on its lower end. rl`he front side of the angle metal bar 2 is secured to the support la and also to the rear side of the angle metal bar 3 by a bolt 5 extending through each of the horizontal tubular parts 1l and secured therein by a nut 5 on the inner end of said bolts.

At the central part of the lay, where the iilling feeler-fork is ordinarily placed, the angle metal bar 2 has an opening 2 therein through its upper part and front side for the filling feeler-fork.

The central block or support 1b, made of metal, preferably a casting, corresponds to the end support 1L and has the two horizontal tubular parts 1b and the two vertical tubular parts 1b and webs 1b and 1W connecting them. Bolts 1b3 and 1b are used to secure the angle metal bar 2 and the angle metal bar 3 to the block or support 1b.

The central portion of the block or support 1b is cast or made with a guide or recessed portion 1b7, adapted to receive the iilling feeler-fork. (Not shown.)

Intermediate the end supports 1a and the central support or block 1b are arranged separate metal supports or blocks l, (see Figs. 7 and 8,) the horizontal tubular part 1.A of which corresponds to the horizontal tubular part 1a of the support l, and the vertical tubular part lf corresponds to the vertical tubular part la of the support la. Each block 1C is secured in position between the angle metal bar 2 and the angle metal bar 3 by a vertical bolt and a horizonal bolt corresponding to the bolts 4 and 5.

At the rear part of the lay-beam extends the reed 6, which may be of the ordinary construction and composed of the vertically-extending teeth 6/ and the upper and lower bar or rod 6, to which the teeth are secured. The lower bar 6 of the reed 6 extends in a groove or recess in the front upper side of the transverse bar 7, preferably made of wood, which rests upon the rear vertically-extend ing web portions 1a of the support l and is secured in position by the bolt 8, having the nut S on its inner end. rIhe lower part of the reed 6 is confined and held in position between the grooved portion or recess in the bar 7 and the rear edge of the upper side of the angle metal bar 2. The upper bar 6 of the reed 6 extends within a recessed portion on the lower side of a transversely-extending metal bar 9, preferably of angle shape in cross-section and secured at its ends by a bolt 10 to the upper end of the lay-horn 1. An angle-strip 11 extends in front of the upper bar 6 of the reed and is secured to the metal bar 9 to hold the reed in place.

Extending along the front surface of the metal bar 9 is preferably a wooden bar 12, rounded on its front side to form the handbar of the lay.

In Figs. 9 and 10 I have shown a modified construction of the lay-beam shown in the other figures. In said Figs. 9 and 10 I have substituted for the metal supports or blocks 1a, 1b, and 1C a wooden beam or bar 13, which preferably extends the full length of the lay and has extending upon its top and front side the angle metal bar 2, forming the race and front side of the lay-beam, and extending upon its lower and rear part the lower angle metal bar 3. A side extension or foot 14 is formed on the upper end of the lay-sword 1 to receive the metal angle-bar 3. The metal angle-bar 2, beam 13, and metal angle-bar 3 are all secured together and are secured to the rear side of the foot or extension 14 by bolts 15, having nuts 15 on their inner ends. (See Fig. 10.) The other parts shown in Figs. 9 and l() correspond to the parts shown in the previous figures and have the same letters of reference thereon.

The advantages of my improvements will be readily appreciated by those skilled in the art.

I produce a lay-beam of simple and inexpensive construction and of great strength and very rigid, which will not warp or get out of shape.

It will be understood that the details of construction of my improvements may be varied, if desired.

Having thus described my invention, what I claim as new, and desire to secure by Iletters Patent, is-

1. In a loom, a lay-beam comprising two independent rigid angle metal bars, one forining the top and front, and the other the bottom and rear of the lay-beam, and means for holding them in position and securing them together, substantially as shown and described. q
